Weyl 级数与迹公式:我们可以将它们相加吗?

摘要

定态密度的周期轨道表达式在直接用于计算热力学相关量时会产生不准确的结果。这是因为迹公式通常仅在能量较大时才有效,而实际计算中却在所有能量范围内使用。本文提出一种方法,通过区分来源于低能量行为(不准确、产生伪影)的贡献与来自次要但物理上准确的贡献,来克服这一问题。该方法通过分析圆形弹跳球的费迪南德子分布函数进行测试,可拓展至其他动力系统。

备注

Substantial changes. There are now explicit asymptotic relations as well as a deeper analysis of the analytic structure of the various relations. We dispensed with the harmonic oscillator in order to have a deeper discussion of periodic orbits in billiards
